RING SPINNING on T wisi-ING APPARATUS.

' Application filed September l5 To /ZZ whom it may concern:

Be it knownth'at we, GEORGE O. DRAPER and CLARENCE E. METCALF, citizens of the United States, and residents of Hopedale, county of Worcester, State of Massachusetts, have'invented an Improvement in Rin Spinning or Twisting Apparatus, of which t e following description, in connection with the like ligures on the drawings representing like parts. I This invention relatesto ring s inning or twisting ap aratus of the type W erein the 'tied with a raceway for the travvoperation, the ring hav ing limited radial and speed it seems to float, aait is technically termed, apparently withoutupport.

,.:Oui invention has for its objects the imwhereby the control of thefring movements is improved, the friction reduced to a minimum, and a smoother and more uniform action of the ring secured. The various novel features of our invciition will be fully described in the subjoined particularly pointed out in e following claims.

Figure 1 is a side elevation of a rotary-ring apparatus embodying one form of our invention. Fig. 2 is a diametral section thereof on the line 2 2, Fig. 3 and Fig; 3 is a top plan View of the casing and the traveler-clearer, showing lalso the annular seat for the ringbearing to be described We have herein shown the ring and ringcarrier as separable, inasmuch as they are to be understood that, il desired, the ring and l eferring to the drawings, the ring 1 may be of a well-known type, having upper and lower doublel flanges 2 and 3, the former providing a raceway for the traveler 4 of suitable lvconstrue tion, the lower flange 3 of the ring in the present instance being shown as tightly ,fitting in an annular socket 5 in the rotatable ring-carrier The latter is shaped to present an annular beveled or inverted i'rustoconical bearing 7 below the socket, said bearingl having depending from its smaller lower l Specification of ,Letters Patent.

,1905.A Serial No. 278,539- I end a thin circular web 8, having. its lower edge outturned to forma continuous annular lip 9. j 1

A fixed metallic casing,fsho.wn as comprising an upright circular portion 10 anda circu a r inturnediiange 11,1Figs. 2 and 3, is secured to the ring-rail -bya metallic holdingplate 12, having suitable ears 13 to retain'the casing in place. The casin carries an annular non-metallic seat 14 fort. e bearing 7, concentric therewith and preferably made convex transversely, as shown in Fig. 2, to form to form an antifrictio-sup ort for the ring in a vertical direction and a so to limit its radial movement. Y The lip 9 forms a movable member, and the iangell a fixed member, of .a -downhold to limit the axialorvertical lifting movement of the ring, the lip extending slightly under` the flange, with sufficient clearance between to permit sufficient movement 'of the ring when rotating.

a tangential contact with the bearing. Pref- `erably this seat is made of wood impregnated 'with wax, grease, or other suitable substance The vertical or axial movement of a rotary i ring is very important, and it should, if possible, be controlled by a continuously or circularly acting means, such as is provided herein by coperation `of the lip and flange, as described.

The web 8 is thin, and the external diameter of the lip 9 is very little greater than the internal diameter of the flange 11, so that in assembling the apparatus the lip can be forced past the flange.

As will be seen from Fig. 2, the coperation of the seat and bearing permits any necessary slight tipping movement of the ring, aswell as its requisite radial movement, while forming a vertical support therefor with a mini-- muni of friction. The seat is forced into the casing and is fixedly held therein.

We have provided a novel and simple traveier-clearer consisting of an upright or clearer 'portion 15 long enough to properly cooperate with the traveler and a curved resilient or elastic base 16, the latter snapping into an external annular groove 17 in the wall l0 of the easing. An upright notch 1S intersects this groove, the clearer portion 15 being held therein by the resiliency of the base, the curvature whcreolnormally is less than that IOO ros

' I 5 we'claim as new,`and desire to secure by Letof' the giioovc. s aresult the-curved base `16 hugathe casing tightly, while the coperation of the notch 18 and clearer portionI 1.5 maintains the latter in roper position. Preferaljy'the base 16 is `ong enough to embraceabout one-half ofthe circumference ofthe casing to provide a firm and secure Y hold orthe clearer.

Our invention is not restricted to the precieeconstruction herein shown, as the same may be modified or varied in dierent particulars by those skilled in the art without departing from the spirit and scope of our invention.

Having fully described our invention, what i A- ters Patent, is#

provided with an annular bearing, a ixed,-

annular casing, a wooden seat carried thereby concentric with and to coperate with the bearing, to vertically sustain and limit radial movement of the ring, and means below the bearing and seat to limit lifting movement of therin- Y 41.2,?'1 e combination, with a rotary ring provided with an annular bearin a e annular casing having an inturne flange, a non-metallic and transversely-convex seat carried by the casing to coperate with and tan entially engage the bearing, and a down- 1 hol depending from the bearing and having an external annular lip to coperate with the under side of said flange and limit lifting movement of the ring. l

5; A rotary spinning-ring, combined with an annular, beveledbearing connected therewith and having a depending circular extension provided with an external li a fixed casing, a transversely-convex ann ar seat of wood carried by the casing to cooperate-With the bearing, the lip on the extension having a continuous circular engagement with the casing when the ring lifts, to limit such movement.

6. The combination, with av rotary ringcarrier having an inverted frusto-conical bearing and a downhold depending1 fromof a ring xedly mounted on t e ringcarrier, a surrounding and transversely-convex Wooden seat for and to tangentially engage the bearing, and fixed annular means be ow said seat to coperate with the downhold and thereby limit lifting movement of the rin y 7. Te combination, with a rotary ring .provided with a beveled, annular bearing, of a fixed casing having a seat for the bearin and having an external annular groove an an intersecting notch, and an upturned traveier-,clearer having a resilient curved base to snap into the groove in the casing-the clearer resting in the notch.

8. The combination, with a rotary ring provided with a beveled, annular bearin of a iixed casing having an annular dow 4old member, a coperating annular member movable with the ring, and a concentric, non-metallic seat for the bearing, to limit radial movement of and also sustain the ring, the fixed and movable downhold members having a circular engagement and limiting lifting movement of the ring.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
